CDC Admits No Studies Proving Vaccines Given in First 6 Months Don't Cause Autism

Attorney Aaron Siri exposes lack of evidence behind CDC's long-held claim that vaccines don't cause autism

Published on Mar. 4, 2026

In a federal court order, the U.S. Department of Justice signed a stipulation on behalf of the Centers for Disease Control and Prevention (CDC) acknowledging that the CDC does not have studies proving the vaccines administered in the first six months of life do not cause autism. Attorney Aaron Siri, who obtained the court order through a lawsuit, says this reveals a lack of safety accountability in the vaccine program.

Why it matters

The 1986 National Childhood Vaccine Injury Act gave vaccine manufacturers immunity from civil liability, removing the economic incentive to conduct long-term safety studies. This has allowed the vaccine schedule to expand significantly without the same rigorous safety standards applied to other pharmaceutical products.

The details

Siri, the managing partner of Siri & Glimstad LLP, spent years demanding the CDC provide the studies it relied upon to claim vaccines do not cause autism. The DOJ eventually produced a list of 20 studies, but 19 were irrelevant and the 20th actually showed an association between the DTaP vaccine and autism. Siri says this reveals the CDC's public claims about vaccine safety are not based on scientific evidence.

  • In 2019, the DOJ signed a court order on behalf of the CDC in the Southern District of New York.
  • The order stipulated the list of studies the CDC relied upon to claim vaccines given in the first 6 months don't cause autism.
  • Siri appeared on the Joe Rogan Experience podcast in early March 2026 to discuss these findings.
